SUMMARY:An asymptotic model for gas-solid flow in blast furnaces
DESCRIPTION:Development of mathematical models which include complex multiphase flow, coupled with heat exchange and chemical reactions, is necessary for understanding the inner state of the blast furnace. In this work, a novel approach using asymptotic methods is developed to model the transient gas-solid flow behaviour in the blast furnace. This is done by reducing the earlier developed Euler-Euler models with scaling assumptions that are based on the fact that the residence time of gas in the blast furnace is usually smaller than that of solid by several orders of magnitude. Results from this reduced model yield gas and solid flow patterns inside the blast furnace. In parallel, another model is developed by combining Discrete Element Method (DEM) and Computation Fluid Dynamics (CFD) to precisely simulate the gas flow and solid motion in the blast furnace. A qualitative comparative study between velocity patterns obtained from both the models is carried out. It is believed that asymptotic modelling could possibly open the doors to a computationally efficient approach for predicting the inner state of the blast furnace.
